Page 11: Section 1.0 - Introduction
Section 1 Introduction System Overview The PMC200/200-P is a 2-axis motion controller designed to drive Newport Model 495 and 496 integrated motorized rotation stages, and 850 Series motorized drives. Utilizing motion control ICs and a Motorola 68000 host processor, the PMC200/200-P performs all the position and velocity control for each axis. -
Page 12: Section 2.0 - System Operation
Section 2 System Operation Overview of The controller keyboard is the primary input device on the PMC200/200-P, PMC200/200-P but a joystick may be used as well. The PMC200/200-P can operate in two modes: Setup mode and Execute mode. In Setup mode, you “configure” the PMC200/200-P for operation. -

RESET AXIS 1 AXIS 2 RS232 IEEE 488 Figure 2-1 — Controller Rear Panel CAUTION The connector on the right-hand side of the controller is for the joystick only. Attaching an actuator or rotary stage to this connec- tor may cause damage to the controller. Refer to Section 2.7 for joystick operation procedures. -

Page 15: Power Up Sequence
Power Up Sequence The PMC200/200-P has battery back-up memory which holds the latest PMC200/200-P configuration parameters. If the front panel power switch is pressed, the PMC200/200-P memory maintains the system parameter configuration set at the time of the last power down. If the RESET button (on rear panel) is pressed, the PMC200/200-P memory will be reset to the system default parameters shown in Table 2-1. - Page 16 REVERSE RUN STATE - If an axis is moving in the reverse direction, pressing this switch will stop the motion. If the axis is moving forward, pressing this switch will cause it to reverse direction. When moving, the velocity of the axis is controlled by the VELOCITY STEP SIZE potentiometer.

Page 17: Output Devices In Execute Mode
2.5.2 Output Devices in Execute Mode Like the front panel switches, the functions of the output devices depend upon the operating mode. Display RUN STATE - The display shows the real time position and real-time velocity of the axis. When the actuator is not moving, the display shows the velocity setting of the VELOCITY/STEP SIZE potentiometer. -
Page 18: Keyboard Functions In Setup Mode
2.6.1 Keyboard Functions in Setup Mode In setup mode, the labels below the switches on the controller front panel perform the following functions. EXIT This switch exits Setup mode and enters Execute mode. Previous Menu This switch selects the previous menu. Next Menu Press this switch to leave the current menu selection unchanged, and go to the next menu. - Page 19 When you enter a menu, the most recent menu selection will be displayed in the setup structure, i.e., the ACTUATOR TYPE menu might show ‘495,’ if that is the most current selection. To change a menu selection, such as the Actuator Type, press [ ] or [ to scroll through the possible choices.
- Page 20 JOG STEP SIZE The JOG STEP SIZE is a pre-defined distance that the motor device will move each time an axis JOG switch is pressed. The menu choices are: For Actuator in millimeters: 0 - 0.01000 mm 0 - 0.10000 mm (default) 0 - 1.00000 mm 0 - 10.0000 mm 0 - 100.000 mm...
- Page 21 BACKLASH Backlash occurs when direction of the actuator is FACTOR reversed, due to “play” in the gear linkages. Backlash is specified as the discrepancy between motion as read from the encoder, and the actual motion of the lead screw. This is determined by an external meas- urement device (i.e., interferometer).

Page 31: Motion Control
Motion Control Using a digital servo circuit, the motion control ICs (HCTL-1000) perform all of the position and velocity control for each axis. The system software directs all position and velocity control by writing to its registers. Positional feedback comes to the motion control ICs from an incremental encoder in the actuator assembly. -
Page 32: Troubleshooting Guide
Section 4 Troubleshooting The following section has been provided to keep the PMC200/200-P system functioning properly and efficiently. The Troubleshooting Guide lists problems that you may encounter and will either suggest an action to correct the problem or will direct you to the solution elsewhere in this manual. - Page 33 If the error occurs in spite of the above procedures the Controller is defective. Do not attempt repair. It is recom- mended that the Controller and Motion devices be returned for repair and testing. Problem: The display reads VRTPWRFAIL or is BLANK or the keyboard does not respond.
